arnr rrrn PAINT COMPOUND.

SPECIFICATION forming part of Letters Patent No. 789,600, dated May 9,1905, Application filed December 19.1904. Serial Ila. 237,576.

To In whom, it 'n'my concern:

Be it known that I, LoUIs SrnNcEn FLATAU, a citizen of the UnitedStates, residing at St. .IJOUIS, State of Missouri, have invented newand useful Improvements in Paint Com.- pounds, of which the following isa specification.

My invention relates to an improved paint compound. It is designed moreespecially for use upon and for treating heated metal surfaces, moreparticularly the front ends and stacks of locomotive and other enginesand like purposes.

Said. invention consists of the compounding, substantially as and in theproportions hereiiiiafter named, of certain ingredients presentlydescribed, and particularlypointed out by the claim.

I11 the carrying out of my invention I suit ably grind or reduce aquantity of crude gilsonite or asphaltum to the requisite finenessunattended with any heating action, thus preserving it intact and from.loss of any of its properties, as would be the casein effecting thereduction of the material by the use of fire or heat, which would bealso more or less hazardous. The thus ground gilsonite is run into amixingn'rill below, such as disclosed in my pending application filed.December 19, 1904', Serial No. 237,575, into which latter has beenpreviou sly placed about six barrels of naphtha. About eight barrels ofthe gilsonite are run into the mixing-mill, further quantities of thenaphtha being added as the quantity of gilsonite may require in order toregulate the gravity of the asphaltum composition or product. About tenbarrels of the naphtha are finally put into the mixing-mill with. thegilsonite to secure the desired or effective product. Into this mixtureI place two or three barrels of linseed-oil after having been boiled andthen add two barrels of what is con'in'ionly called gloss-oil,preferably prepared as later .noted, and any good drier. Saidmixing-null is suitably covered to prevent evaporation or escape ofgases to annoy the attendants or workman and alter the whole has becomethoroughly amalgamated into a perfect asphaltum composition, as it were,which is effected by rapidly running or rotating the mill. In theproduction. of said. gloss-oil I suitably reduce or comminute, as finelyas may be required, crude resin and run it into a mill such, forinstance, herein designated-which has been suitably supplied. withbenzin and dissolve the resin therein by agitation unaided by anyheating action, and as the oil. is thus produced run it into barrels foruse as needed.

My aforesaid paint compound, which is characterized in its applicationby a black glossy surface, will effectively resist six or seven hundreddegrees of heat, and is therefore, as I have found by actual use, highlyserviceable for painting, especially the front ends of smoke-stacks oflocomotive and other engines, as well as for all steel or wood work andwhich is incomparable for durability and appearance, while, aspreviously noted, the element of the use of fire in its manufacture isentirely eliminated, which would be greatly objectionable for thereasons as aforesaid herein given.

Latitude is allowed as to details herein, as the same may be varied ascircumstances suggest Without departing from the spirit of my invention.

I claim- The lmrein-described process of producing a paint compound,which. consists in reducing gilsonite by grinding to a powder; combiningwith naphtha said gilsonite in powder form by sifting the latter uponsaid naphtha; and adding to the aforesaid ingredients boiled linseed-oiland gloss-oil, and then thoroughly amalgamating this mixture by theagitating action of a mill.

In testimony whereof I affix my signature in presence of two subscribingwitnesses.

LOUIS SPENCER FLAIAU.
